Siesikai (Ukmerge District) - on a white field a red pale
(white-red-white 1-2-1 approximately) with silver centaur aiming
with a golden bow to his own tail. Flag proportions 5:6, free
edges bordered with a narrow golden stripe, finial is a golden
tip and golden bands. The charge comes from the arms of the ducal
Daumantas-Siesickis house. Siesikai was the home of those local
dukes till the early 17th century. The centaur is the arms of a
few ancient noble houses of Lithuania, and it originates most
likely from the Byzantine-Russian culture, which had some
influence in Lithuanian culture before choosing the Catholic
baptism in 1386.Virginijus Misiunas, 30 December 2009
